What I found was from another website and it said "For most of the year, Atlantic puffins live on the open ocean, with a range spanning from the eastern coast of Canada and the northern United States to the western coast of Europe and northern Russia. 60% of the world's puffins live near Iceland. Puffins are specially adapted to living<span> on the open sea." here is the link https://animalfactguide.com/animal-facts/atlantic-puffin/

I put the link and a picture so it hopefully won't be deleted for plagiarism.

A parent pushes a balanced frictionless playground merry-go-round. The parent exerts a force F tangent to the merry-go-round res
Alexandra [31]

Answer:

F = 150 N

Explanation:

Torque being applied by parent

= F  x r

where F is force applied tangentially and r is point of application of force from axis of rotation ( center )

given torque = 240 Nm

r = 1.6 m

F x r = 240

F x 1.6 = 240

F = 150 N

So a force of 150 N is applied by the parent to achieve the given torque.

This force will also be applied by the merry - go- around  on the parent as reaction force according to Newton's third law. The parent will not be pushed back by this force  because he is standing on a rough surface . Friction of surface will help him remain stationary on the ground.

a college student exerts 100N of force to lift his laundry basket the weighs 75N. at what rate is the basket accelerated upwards
sleet_krkn [62]
You can use the formula A=F/M, the rate that it is being accelerated upward is 3.3, so about 3.

The mass of the basket = weight/acceleration due to gravity. (75/10=7.5 kg)

100 (upward force from girl) minus 75 (downward force from basket) is 25.
So 25=7.5a, which becomes 25/7.5, which equals 3.33 kg x m/s.

And when rounded, the momentum is about 3, (or 3 p).

Hope this helps!
